DIAGNOSIS: Prionapteryx differs from Mesolia and Zovax in the male genitalia with a basal costal process on the valva and without coremata. The basal costal process is shared with Surattha, but the latter differs in having a strongly arched uncus and the phallus with a pointed tip. The female genitalia can be distinguished from those of Mesolia, Zovax and Surattha by the triangular papillae anales, the long, tubular 8th abdominal segment and by the very strongly developed intersegmental membranes between abdominal segments VII and VIII and abdominal segments VIII and IX. REMARKS: The genus Prionapteryx includes 57 species (Nuss et al., 2012) since Błeszyński (1967: 92) synonymized in this genus a number of genera. Some of these species have to be returned to Surattha Walker since this name was revised as valid by Bassi & Mey (2011: 234). On the other hand, Loxophantis has to be considered as a junior synonym of Prionapteryx as shown by the study of both external features and genitalia of the type species.
